WORKBENCH, CRANE, AND ENGINE-STAND COMBINED.

Application filed October 8, 1918.

To all whom it may concern:

Be it known that I, JOHN M. MATTIS, a citizen of the United States, and resident of Sioux City, Woodbury county, Iowa, have invented anew and useful Workbench, Crane, and Engine-Stand Combined, of which the following is a specification.

The object of this invention is to provide an improved work bench carrying an engine stand for supporting and manipulating the power plant of a motor vehicle; a crane for lifting, carrying and depositing the power plant; and a vise for holding objects to be worked upon.

A further object of this invention is to provide a'work bench and engine stand combined, one member of the engine stand being supported in fixed relation on the bench and the other member thereof being sup ported for sliding movement on said bench relative to the fixed member.

A further object of this invention is to provide an improved construction for an engine stand in which a rotatable member carries clamping arms adjustable radially relative to the axis of rotation.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which igure 1 is a plan of a combined work bench, crane and engine stand embodying my invention. Fig. 2 is an elevation of the same, a portion of the crane being broken away to economize space. Fig. 3 is a detail section, on. an enlarged .scale, on the line 33 of Fig. 1, showing the means for mounting the adjustable clamping arms.

Fig. 1 is an. end elevation, partly in section, of a portion of the device,

In the construction of the device as shown a bench is formed of a frame 10, preferably of angle iron members, such as legs and braces, and a top 11, which may be formed of planks. A vise 12, of any suitable form, may be carried in desired location on the bench. A crane 13 of any common and well known construction, is mounted in any suitable location on the bench, preferably near one corner thereof so as to leave the major portion of the top 11 free for support of work objects and tools.

An engine stand is fixed to and supported by the bench and is constructed as follows: A beam or frame member 1% is fixed to and Specification of Letters Patent.

crosses one end of the frame 10,'preferably adjacent the crane 13, and projects beyond said frame and has its projecting end por tion supported by a leg 15, thus forming a fixed standard for the engine stand at one end of the bench. A rod 16 isfixed in and longitudinally of the frame 10 at substantially the elevation of the beam 14, and a beam 17 is pivoted at one end and slidable on said rod, projects from the bench frame parallel (in its normal position) with the fixed beam 14, and has its other end supported by a leg 18, thus forming an adjustable or sliding standard for the engine stand adjustable on the bench relative to the fixed standard. A brace 20 preferably connects the lower end of the leg 15 to the opposite lower corner of the bench frame 10.

A bracket 21 is secured to the outer face and near the projecting end of the beam 14 and a shaft 22 is journaled in said beam and bracket. A worm gear 23 is fixed to the shaft 22 and is adapted to be driven by a worm shaft 24 journaledin the bracket 21 and provided with a removable hand crank 25.

A rod or spindle 26 is mounted in the beam 17 of the slidable standard in alinement with the shaft 22 and a clamping head 27 is pivoted on said rod or spindle. The clamping head 27 may be of any suitable form for engaging and supporting one end portion of an automobile engine or motor in a ronnnonmanner, and is here shown conventionally. An adjustable clamping head is carried by the shaft 22 and is adapted to cooperate with the clamping hea d 27 by engaging and supporting the opposite end portion (the larger end) of the engine or motor to be worked upon. In this construction a disk or plate 28 is fixed to the shaft 22 on the inner side of the fixed standard of the engine stand, said disk or plate being formed with a central aperture to receive said shaft, upon the end of which is secured a nut 29 or other fastening device.

The disk or plate 28 also is formed with a periplreral annular row of apertures 30. A cross-head 31 is mounted on the shaft 22 against the inner face of the plate 28 and is held thereto by the nut 29 and by bolts 32, 33 mounted through diametrically opposite holes 30 of said plate. Supporting arms 34, 35 are mounted on opposite end portions of the cross-head 31 and are held thereto by the bolts 32, 33 respectively and by other bolts 36, 37. The supporting arms 34:, 35 are separately adjustable longitudinally of the cross-head 31 by selective engagement of the bolts in holes 38 in said arms, and are adapted to engage and support the larger end portion of the engine or motor and cooperate with the clamping head 27 in holding the engine or motor in the device. The supporting arms 34, 35 may be of any desired construction, so far as the supporting function is concerned, and are here shown conventionally.' In addition to this longitudinal adjustment of the supporting arms on the cross-head, one of said arms, in this case 34, is so constructed that it may be adjusted angularly of the plate 28, that is to say out of alinement with the other supporting arm 35 and the cross-head 31. In such adjustment the supporting arm 34 is held to the plate 28 by the nut 29 and by the bolt 32 engaged in one of the holes 30 disassociated from the connection of the cross-head. This is desirable where the contour of the object to be gripped is such that it does not present two diametrically opposite points suitable for supporting engagement. It is obvious that still another supporting arm may be mounted on the plate 28 if the character of the work object is such as to require the employment thereof.

In practical use the crane 13 is employed in lifting, conveying, holding and depositing the work object, such as the engine or motor of a motor vehicle, in the'operation of securing such work object in the engine stand. The supporting arms 34:, 35 are caused to engage one end portion of the work object, having been adjusted either lonleg 18 being gitudinally or radially as required by the shape of the object. The clamping head 27 is caused to engage the opposite end of the object, the standard formed of the beam 17 and moved lengthwise of the rod 16 as required by the length of the object. The object is then held in convenient position for work thereon, and may be rotated as desired on the axis of the shaft 22 and spindle 26 by turning the crank 25. Detached portions of the object may be placed upon the bench or within the vise 12 for convenience in working on them. Thus a convenient and compact arrangement of devices is provided for manipulating and working upon the object. When not in use the standard carrying the clamping head 27 may be moved on the rod 16 into a position adjacent the fixed standard, where it will be out of the way and permit access to the bench or vise.

I claim as my invention 1. A device of the class described, comprising a frame, a standard for an engine stand fixed to and projecting from one end portion of said frame, said frame including a rod extending lengthwise near one margin, and a second standard slidable on said rod toward or'away from the first standard.

2. A device of the class described, comprising a frame, a beam fixed to one end of said frame and projecting therebeyond, a leg supporting the free end of said beam, a rod mounted in said frame at right angles to said beam, a second beam parallel with the first and pivoted at one end to and slidable on said rod, and a leg supporting the free end of the second beam.

3. In an engine stand, a shaft, a plate fixed thereto, said plate being formed with an annular row of holes, and supporting arms secured to and adjustable angularly on said plate, together with fastening means carried by said arms and adapted for selective engagement in said holes.

4:. In an engine stand, a shaft mounted for rotation, a cross-head fixed thereto, and supporting arms secured to and adjustable longitudinally of said cross-head;

5. In anengine stand, a shaft, a plate secured thereto, a cross-head secured to said plate, and supporting arms secured to and adjustable longitudinally of said cross-head, one of said supporting arms also being adjustable angularly of the plate independently of the other supporting arm and the cross-head. 7
